Hi-Speed USB OTG controller
10.7.2
DcChipID register (R: 0270h)
This read-only register contains the chip identification and the hardware version numbers.
The firmware should check this information to determine the functions and features
supported. The register contains 3 B, and the bit allocation is shown in
Table 139
.
10.7.3
Frame Number register (R: 0274h)
This read-only register contains the frame number of the last successfully received
Start-Of-Frame (SOF). The register contains 2 B, and the bit allocation is given in
Table 140
. In the case of 8-bit access, the register content is returned lower byte first.

PSOF
Pseudo SOF interrupt:
Logic 1 indicates that a pseudo SOF or
μ
SOF
was received. Pseudo SOF is an internally generated clock signal
(full-speed: 1 ms period, high-speed: 125
μ
s period) synchronized to
the USB bus SOF or
μ
SOF.
SOF interrupt:
Logic 1 indicates that a SOF or
μ
SOF was received.
Bus Reset
: Logic 1 indicates that a USB bus reset was detected.
When the SW_SEL_HC_DC bit in the OTG Control register is set,
BRESET will not be set, instead, this interrupt bit will report SE0 on DP
and DM for 2 ms.
